Basic methods of attaining knowledge and skills

Human being perceives:

by eyesight (80 %),
by hearing (12 %),
by other senses(8 %),

of all pieces of knowledge. But this fact is in diametral contradiction with methods of the education often used in the whole world, i.e. that the new information is explained:

by hearing (84 %),
by eyesight (10 %),
by other senses (6 %).

Such reality has the bad influence on the effect of the traditional education system, that's why a human being remembers

10 % from that, what a human being first time hears or reads,
20 % from that, what a human being concurrently reads and hears,
30 % from that, what a human being sees in pictorial form.

But a human being remembers as much as

70 % from that, what a human being concurrently sees and hears,
80 % from that, about what a human being also tells or relates,
90 % from that, what a human being also performs alone.
